Definitions

  • the invention relates to a sealer for closing a container.
  • the invention further relates to a method for closing a container with a sealer according to the invention.
  • the cans pass through a can seamer after being filled with the beverage or food, with the filled can bodies entering via a feed path and can lids entering via another feed path.
  • the can seamer usually has several similar stations arranged in a carousel shape, in each of which a can is closed with a can lid.
  • the can lids are guided onto the can body and held on the can body with a holding plate of a folding head. This holding also serves to fix the cans against breaking out of the circular path traversed by the cans in the can seamer due to the centrifugal force.
  • the can body with the can lid is folded at the edge over a folding roller and thus closed.
  • the can with the can lid is additionally rotated around its own axis of symmetry using the folding head.
  • the folding heads are arranged on a respective folding shaft.
  • the folding rollers are arranged on a folding lever via folding lever shafts.
  • a generic can seamer is in the DE 749636 and the DE4234115 A1 described.
  • the can seamer includes a clamping device for holding a can to be closed. In the operating state, the can to be closed is inserted into the clamping device and secured by it in the axial and radial directions.
  • a can lid is also centered over the can opening of the can to be closed.
  • the can has a circumferential can flange in the area of the can opening and the can lid has a circumferential one Can lid flange.
  • the can seamer additionally comprises two folding rollers, each mounted rotatably about an axis, which press the can flange and the can lid flange together by means of a substantially radially acting force, the compression being achieved by continuous rolling in the circumferential direction along the circumference of the can opening he follows.
  • the can seamer is from the GB 2098899 A known.
  • the can seamer includes a clamping device for holding the can to be closed and a folding roller. In the operating state, the can to be closed is inserted into the clamping device and secured by it in the axial and radial directions.
  • a can lid is also centered over the can opening of the can to be closed.
  • the can has a circumferential can flange in the area of the can opening of the can body and the can lid has a circumferential can lid flange.
  • the well-known can seamer 1000' according to Fig. 1 comprises a lid supply device 11' for supplying a lid 101' to the can, a gassing rotor 15' for supplying gas to the can and a folding process 14' for closing the can with the lid 101'.
  • the lid 101' is introduced into the can seamer 1000' along the arrow C' by the lid feed device 11'.
  • the covers 101' are arranged on the gassing rotor 15'.
  • the lids 101' are transported further by rotating the gassing rotor 15'.
  • the cans are fed through the container feed 12' into the container receptacles 17' of the gassing rotor 15'. brought in.
  • There the can is gassed in area D' with a gas such as carbon dioxide or nitrogen and combined with the lid 101'.
  • the gassing takes place along the arrow B 'with the gas supply 16'.
  • the can with the lid 101' is passed through the container transfer 13' from the gassing rotor 15' to the folding process 14' and closed there.
  • the cans are clamped between a lower machine part 4' and an upper machine part 5' on a rotor 42' of the folding process 14' and closed by the folding process 14'.
  • the closed can is conveyed into the can outlet 18' by another rotor.
  • the can seamer 1000' according to Fig. 1 and 2 includes both a housing 1', which surrounds a work space 2', and supporting structures 3'.
  • the machine upper part 5' is positioned on several cylindrical telescopic columns 3' as supporting structures.
  • the height of the upper machine part 5' is adjusted depending on the container to be processed (i.e. can and lid).
  • the cans are 1000' open when transported to the can seamer. That's why the entire work area 2' is a hygiene zone. Therefore, the can seamer 1000' is provided with the housing/cladding 1' to delimit the hygiene zone and to ensure personal safety.
  • This panel 1' is attached to the lower machine part 4' and covers the entire working area 2' including the upper machine part 5'.
